Air quality today
The air quality in Bottrop today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 6.31 µg/m³ and a PM10 value of 9.822 µg/m³, based on five valid observations.
Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The air‑quality record for Bottrop in North Rhine‑Westphalia currently draws on a single monitoring station – the Bottrop‑Welheim site – which supplies one row of data for each of six measured pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). Because there is only one station, the dataset does not capture spatial variation across the city; it reflects conditions at that specific location.
All six pollutants have recent measurements dated 2026‑02‑10 17:00 UTC except for NO, whose latest entry is from 2024‑03‑11 11:00 UTC. The values are identical across the minimum, median and maximum statistics, indicating a single observation per pollutant rather than a distribution over time. For example, NO₂ registers at 18.858 µg/m³, O₃ at 29.711 µg/m³, PM₁₀ at 9.822 µg/m³, PM₂.₅ at 6.31 µg/m³ and SO₂ at 2.429 µg/m³, while NO is recorded at 10.629 µg/m³.
Because the dataset consists of one row per pollutant, there is no spread to report – each metric’s 10th and 90th percentiles match the single value. The overall freshness is mixed: five pollutants have data updated within the last three days, whereas NO remains over a year old. Consequently, while the current snapshot provides a clear picture of concentrations at the Bottrop‑Welheim site, it does not represent broader city‑wide conditions or temporal trends. Users should keep in mind that air quality can differ across neighborhoods and change throughout the day.
